Power the World

SMR™: SOLO MICRO-MODULAR REACTOR

Nuclear-Powered Technology

Engineered to run autonomously, our SMR™ - SOLO Micro-Modular Reactor uses nuclear technology to power the world with environmental awareness, efficiency, maximum power, and safety.

DESIGNED ON EXISTING SUPPLY CHAIN

Proven design and engineering: Our pragmatic approach draws on over 50 years of experience and lessons learned from the nuclear industry.

Leveraging existing supply chains, we are building a network of leading industry partners and top-tier suppliers for critical components.

PROVEN LICENSING PATH

Our licensing strategy leverages the ‘Rule of Precedent’: SOLO's robust design meets diverse criteria and adapts to varying licensing environments worldwide, enabling deployment anywhere.

Highly modular and factory mass-produced, SOLO can be rapidly deployed on a global scale, ensuring predictable timelines and rapid ROI.

SAFE BY DESIGN & PHYSICS PRINCIPLE

No exclusion zone required. The Emergency Zone Plan is confined within the operational boundary, defined by a 2.5 meter-thick concrete biological shield encircling the reactor.

Radiation exposure at the shield's outer surface is at least an order of magnitude below legal public safety limits (<1 mSv/year).

DECOMMISSIONING & WASTE MANAGEMENT

SOLO is the first micro modular nuclear reactor with a design that integrates backend considerations from the outset.

This approach minimizes liability for customers and enhances public acceptance.

THE HEART OF SOLO

Our Core

Years of design, weeks to build.

SOLO features a thermally-moderated, gas-cooled nuclear reactor core that operates with standard enrichment U235 (below 5%) and conventional Zircaloy-cladded UO2 fuel pellets, similar to those used in many large-scale reactors worldwide.

The reactor's design efficiently decouples cooling and moderation functions, providing inherent safety features that significantly reduce its risk profile. This enables a straightforward safety analysis, where the safety case can be established based on fundamental principles, without the need for complex evaluation models.

SOLO’s core is inherently safe, incapable of melting or exploding. It is engineered to deliver constant power throughout its operational life, utilizing a minimalist instrumentation and control (I&C) system while operating fully autonomously.

THE SHELL

Monolith

BIOLOGICAL SHIELD

Solo’s biological shield is a 2.5m thick concrete wall around the reactor vessel.
Effective dose below the public exposure limits < 1 mSv/year
Heat evacuation system for both normal and accident conditions based on natural convection Max Concrete Wall Temperature < 314 K.
- Heat can be removed by forced circulation even though natural circulation is enough to remove the decay heat.
Heat losses in nominal conditions are less than 200kW (~6% of core power - i.e. larger than the decay heat).
Decay heat after 1 day post-shutdown is 0.4% of the nominal power (i.e. equivalent to about 10 conventional toasters).

SECURITY

Safeguards by Design

CORE REACTOR SAFEGUARDS VERIFICATIONS

• The reactor will include safeguards based on the Fuel Verification system implemented by the IAEA.
• SOLO features 4-8 safeguard reactor channels around the core, with gamma and neutron multiplicity counting, allowing a unique fingerprint of in-core fuel presence.
• Measurement channels are transmitting in real time to IAEA Headquarters with data encryption and possible authentication via satellite.
• System is locked and sealed in an anti-tampering housing and allows on-site inspection verification.

UO2, LEU+, HALEU

Bridging Technologies

Chart: SOLO with LEU+ and HALEU

SOLO provides the first platform able to transition from current to future fuel products and supply.

SOLO fills the gap between the current use of standard UO2 fuel, future LEU+ and HALEU.

Our micro modular nuclear reactors can work with different fuel taking benefit of LEU+ and HALEU for both larger power (10MW or 20 MW) with same duration or larger duration (30+ or 60+ years) and equal power of SOLO X-1.

SOLO USE CASES

Countless Applications

DATA CENTERS & CRYPTO MINING

SOLO micro-modular nuclear reactor is designed to address the growing energy demands of data centers, particularly those driven by big data and AI technology from companies like Amazon, OpenAI, Apple, and Microsoft. These tech giants are pushing the limits of data storage and processing, requiring vast amounts of energy to support the continuous operations of AI systems.

By placing SOLO reactors in a modular setup next to these data centers covering a diameter of less than 1km range, we can generate up to 1GWe of reliable, carbon-free energy. This solution mitigates reliance on traditional energy grids, ensuring that data centers have the power they need to support AI advancements while reducing their environmental footprint.

SOLO’s deployment offers a scalable and sustainable energy source to meet the demands of modern data-driven enterprises.

INFRASTRUCTURE

SOLO micro-modular nuclear reactors are designed to deliver reliable, carbon-free energy and heat to critical infrastructure projects and remote locations where traditional power sources are limited or unreliable. From rural and island communities to harbors, defense installations, and large-scale infrastructure developments, SOLO provides a scalable and resilient energy solution.

By deploying SOLO reactors near water treatment and desalination plants, we enable sustainable access to clean water, while supporting construction and industrial operations with consistent, high-output power. Defense installations and critical facilities benefit from secure, off-grid energy, reducing dependence on vulnerable supply chains.

SOLO’s modular design ensures a cost-effective, rapidly deployable energy source that strengthens infrastructure resilience and accelerates development in energy-challenged regions.

INDUSTRIAL & MINING

SOLO micro-modular nuclear reactors provide a high-output, carbon-free energy solution for industrial facilities, mining operations, and material production—sectors that demand vast amounts of heat and electricity. From steel, aluminum, and cement manufacturing to chemical processing and rare earth extraction, SOLO ensures reliable power in industries where energy costs and environmental impact are critical factors.

Mining and heavy manufacturing often rely on diesel generators and unstable grids, leading to high operational costs and emissions. By deploying SOLO reactors directly at mining sites, refineries, and industrial hubs, companies gain energy independence, ensuring 24/7 power for production lines, smelting processes, and advanced material fabrication. Additionally, SOLO’s ability to provide both electricity and process heat boosts efficiency, reduces reliance on fossil fuels, and supports decarbonization efforts.

With its scalable, modular design, SOLO offers cost-effective, resilient, and sustainable energy, empowering industries to meet growing global demand while transitioning to a cleaner future.

MEDICAL & HEALTH

SOLO micro-modular nuclear reactors provide a secure, uninterrupted energy and heat source for the medical and healthcare industry, ensuring 24/7 operations for hospitals, clinics, and research facilities. Reliable power is critical for life-saving equipment, surgical procedures, cold storage for vaccines, and pharmaceutical manufacturing, where even brief outages can have severe consequences.

Beyond energy supply, SOLO supports radioisotope production—essential for cancer treatments, medical imaging, and advanced therapies. With growing global demand for radiopharmaceuticals, particularly technetium-99m for diagnostics and lutetium-177 for cancer therapy, SOLO can help decentralize isotope production, making these critical treatments more accessible.

Pharmaceutical manufacturing also benefits from SOLO’s carbon-free, high-temperature heat, which enhances sterilization processes, drug synthesis, and large-scale production while reducing reliance on fossil fuels.

With its scalable, modular deployment, SOLO provides a resilient, sustainable energy solution that strengthens healthcare infrastructure, advances medical innovation, and improves patient outcomes worldwide.
